<p><code class="function">lwres_net_ntop()</code>
      converts an IP address of protocol family
      <em class="parameter"><code>af</code></em> &#8212; IPv4 or IPv6 &#8212; at
      location <em class="parameter"><code>src</code></em> from network format to its
      conventional representation as a string.  For IPv4 addresses,
      that string would be a dotted-decimal.  An IPv6 address would be
      represented in colon notation as described in RFC1884.
    </p>
<p>
      The generated string is copied to <em class="parameter"><code>dst</code></em>
      provided
      <em class="parameter"><code>size</code></em> indicates it is long enough to
      store the
      ASCII representation of the address.
    </p>
</div>
<div class="refsect1" lang="en">
<a name="id2543411"></a><h2>RETURN VALUES</h2>
<p>
      If successful, the function returns <em class="parameter"><code>dst</code></em>:
      a pointer to a string containing the presentation format of the
      address.  <code class="function">lwres_net_ntop()</code> returns
      <span class="type">NULL</span> and sets the global variable
      <code class="constant">errno</code> to <span class="errorcode">EAFNOSUPPORT</span> if
      the protocol family given in <em class="parameter"><code>af</code></em> is
      not
      supported.
